Thats the coolest thing to happen to Doha. Tonnes upon tonnes of words, pages and books. But it costs a bomb too.

Another option is Jarir book stall in ramada. It has a very decent collection too. Am not sure of the other places. I have been here and have loved the places to bits.

I am as big an addict as you, but it merely is not affordable for me in Doha. That's all folks, hehe!
